This summary uses the existing diagnostic information shown in full below.
The car's computer thinks there's a problem with a sensor that measures the electric current in one part of the motor. It's like when a video game controller says a button is stuck, even if it isn't.
This code indicates that the sensor measuring the current in the 'Y' phase of the drive motor is reading higher than expected.
The P2E22 code is triggered when the Powertrain Control Module (PCM) detects a voltage signal from the Drive Motor A Phase Y Current Sensor that is higher than the predetermined threshold. This sensor is crucial for monitoring the electric current flowing through the motor's phase Y, ensuring it operates efficiently and safely.
• Reduced vehicle performance
• Warning light on the dashboard
• Unusual noises from the motor
• Faulty current sensor
• Wiring issues such as shorts or open circuits
• Malfunctioning PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the current sensor for proper operation.
• Replace the faulty current sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Volt
• Nissan Leaf
• Tesla Model S
• Regular maintenance checks
• Ensure proper electrical connections
• Avoid overloading the vehicle's electrical system
Sensor Issue
• Do not ignore the warning light.
• Seek professional diagnostic services.
• Avoid driving the vehicle until repaired.
Check with your vehicle manufacturer for warranty coverage on electrical components.
This code has become more common with the rise of electric and hybrid vehicles, highlighting the importance of electrical system maintenance.
Moderate – Addressing this issue promptly can prevent further damage.
Driving with a malfunctioning motor sensor can lead to reduced performance and potential safety hazards.
• Vehicle in a safe, stationary position
• Engine off and cool
The current sensor is typically located near the drive motor or integrated within the motor assembly.
Q: Can I drive with a P2E22 code?
A: It's not recommended as it may lead to reduced performance and potential motor damage.
Q: How can I reset the P2E22 code?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
